It remains one of the largest single causes of maternal and fetal morbidity and mortality 4. Clinical prediction of disease complications may facilitate instigation of timely management to avert mortality and morbidity in the mother and the baby. Hyperuricaemia is one of the characteristic findings in the preeclampsia 5. In clinical practice, uric acid determination is considered to be a part of the work up in women with preeclampsia to monitor disease severity and aid management of these women. Reduced uric acid clearance secondary to reduced glomerular filtration rate, increased absorption and decreased secretion may be the reasons for elevated serum uric acid levels in women with preeclampsia 6. Hyperuricaemia is one of the most consistent and earliest detectable changes in preeclampsia and has been cited as a better predictor of fetal risk than proteinuria 7. Several studies have reported a positive correlation between elevated maternal serum uric acid levels and adverse maternal and fetal outcomes 8. OBJECTIVES Text… RESULTS Our study included 150 pregnant women with a blood pressure of 140/90 mmHg or higher after the 20th week of gestation on two separate occasions. The mean age of the patients was 27.48+4.3 years and the mean gestational age was 35  2.85 weeks. The uric acid level of the patients ranged from 2.5 to 12.8 mg/dl. The mean uric acid level of the patients was 6.3  1.8 mg/dl. Keeping the cutoff limit for hyperuricemia as serum uric acid level > 5.5 mg/dl; we had 103 (68.7%) patients with hyperuricemia. Among 103 patients who had hyperuricemia IUGR was seen in 99 (96.11%), IUD in 18 (17.48%), stillbirth in 2 (1.94%) and 72 (69.9%) were admitted to NICU. Among 47 patients who had no hyperuricemia IUGR was present in 32 (68.08%), 9 (19.14%) had IUD, 1 (2.12%) had stillbirth and 16 (34%) were admitted to NICU. Hence IUGR and admission to NICU were more significantly more frequent among those with hyperuricemia; p< 0.05. The mean birth weight of babies was 1.73  0.48 and 2.02  0.55 kg among hyperuricemic versus non-hyperuricemic mothers; p= 0.002.

MATERIALS AND METHODS To determine the frequency of hyperuricaemia in patients with pregnancy induced hypertension To compare the early neonatal outcome between patients with hyperuricaemia and those without hyperuricaemia among patients with pregnancy induced hypertension Pregnancy induced hyperetnsion Hyperuricaemia +ive Early neonatal outcome Hyperuricaemia -ive Early neonatal outcome Study Design: Descriptive case series Setting : Department Of Obstetrics & Gynaecology, Benazir Bhutto Hospital, Rawalpindi Study Duration : 15 th Mar 2011 to 14 th Sep 2011 Sample Size: 150 pregnant women Pregnant women with pregnancy induced hypertension defined as a BP > 140/90 diagnosed at the gestational age > 20 weeks will be recruited through emergency or the outpatient department. These patients had their uric acid levels measured with an autoanalyzer using a phosphotungstic acid reagent. All patients underwent antenatal ultrasound with doppler studies in the last trimester to identify IUGR fetuses. These patients were followed till the time of delivery. The birth weight, NICU admissions and stillbirths/ intrauterine deaths were documented. Inclusion Criteria: Pregnant women after 20 weeks gestational age. Women with pregnancy induced hypertension as defined above with a BP > 140/90 on two occasions diagnosed > 20 weeks gestational age. Women of any age and parity. Exclusion Criteria: Patients with pre-existing hypertension before 20 weeks of gestation. A known history of kidney disease identified on history of deranged renal functions. Women on drugs known to increase uric acid levels like thiazides, aspirin and pyrazinamide. Patients who did not include their follow up till the time of delivery were not included in the study. 150 patients with pregnancy induced hypertension, were recruited through OPD and emergency Antenatal ultrasound with doppler studies to identify IUGR Early neonatal outcome Serum uric acid estimation Hyperuricaemia (n=103) Normal uric acid group (n = 47) p value IUGR99 (96.1%)32 (68.1%)0.01 Intrauterine death / still birth 20 (19.4%)10 (21.3%)0.966 Admission to NICU 72 (69.9%)16 (34%)0.01 Birth weight1.73 ± 0.482.02 ± 0.550.002 Hyperuricaemia is frequent among patients with pregnancy induced hypertension Babies of patients with pregnancy induced hypertension with hyperuricaemia had: significantly higher IUGR more frequent admissions to NICU significantly low birth weight. DISCUSSION Including uric acid in the evaluation of preeclampsia, we can identify a high risk group that is likely to end up in fetal complications. In the evaluation of gestational hypertension without proteinuria, the absence of hyperuricaemia can identify a low risk GROUP. Despite the fact that hyperuricaemia is not part of diagnostic criteria for preeclampsia and thus, not typically considered a useful aid to management, several observations have suggested that the presence of hyperuricaemia may identify a form of pregnancy association hypertension with increased risk of preeclampsia.
